This article mainly introduces the LNMP architecture of linux system, MySQL, PHP installation handouts, I hope you can supplement and update some knowledge, if you have other questions you need to know, you can continue to follow my updated article in the industry information.

Introduction to LNMP Architecture

The only difference from LAMP is that N in LNMP refers to Nginx (a web service software similar to Apache). At present, there are many applications of this kind of environment. The original intention of Nginx design is to provide a fast, efficient, multi-concurrent Web service software. In the processing of static pages, Nginx is better than Apache, but in the processing of dynamic pages, Nginx has no advantage over Apache. But at present, there are still many enthusiasts who are more enthusiastic about Nginx. With the continuous maturity of Nginx technology, its position in the field of Web service software will become higher and higher.

And php exists as a stand-alone service called php-fpm. Nginx handles static requests directly, and dynamic requests are forwarded to php-fpm.

MySQL installation

1. Delete the previously installed MySQL [root @ gary-tao ~] # ps aux | grep mysql / / check whether the service starts root 2233 0.0 112680 972 pts/0 R + 19:16 0:00 grep-- color=auto mysql [root@gary-tao ~] # rm-rf / usr/local/mysql [root@gary-tao ~] # rm-rf / etc/init.d/mysqld2.

PHP installation

The PHP installation of Nginx is different from the PHP installation in the previous chapter, because the PHP in Nginx is given to Nginx in the way of fastcgi, which can be understood as that Nginx proxies PHP's fastcgi, while httpd calls PHP as its own module.

1. Because php has been installed before, this reinstallation will directly execute the command in the source package directory: make clean, delete the contents of the previously compiled files, and return to the previous unzipped state. [root@gary-tao ~] # cd / usr/local/src/ [root@gary-tao src] # lsapr-1.6.3 apr-util-1.6.1.tar.gz mariadb-10.2.6-linux-glibc_214-x86_64.tar.gz php-5.6.30.tar.gz phpredis-developapr-1.6.3.tar.gz httpd-2.4.29 mysql-5.6.35-linux-glibc2.5 -x86_64.tar.gz php-7.1.6 phpredis-develop.zipapr-util-1.6.1 httpd-2.4.29.tar.gz php-5.6.30 php-7.1.6.tar.bz2 [root@gary-tao src] # cd php-5.6.30 [root@gary-tao php-5.6.30] # lsacinclude.m4 configure .in libs makerpm php.ini-production README.STREAMS stamp-h.inaclocal.m4 CREDITS libtool meta_ccld README.EXT_SKEL README.SUBMITTING_PATCH stub.cbuild ext LICENSE missing README.GIT-RULES README.TESTING testsbuildconf EXTENSIONS ltmain.sh mkinstalldirs README.input_filter README.TESTING2 travisbuildconf.bat footer main modules README.MAILINGLIST_RULES README.UNIX-BUILD-SYSTEM TSRMCODING_STANDARDS generated_lists makedist netware README.md README.WIN32-BUILD-SYSTEM UPGRADINGconfig.guess genfiles Makefile NEWS README.namespaces run-tests.php UPGRADING.INTERNALSconfig.log header Makefile.frag pear README.NEW-OUTPUT-API sapi Vcscleanconfig.nice include Makefile.fragments php5.spec README.PARAMETER_PARSING_API scripts win32config.status INSTALL Makefile.gcov php5.spec.in README.REDIST.BINS server-tests-config.php Zendconfig.sub install-sh Makefile.global php.gif README.RELEASE_PROCESS server-tests.phpconfigure libphp5.la Makefile.objects php.ini-development README.SELF-CONTAINED-EXTENSIONS snapshot [root@gary-tao php-5.6.30] # make cleanfind. -name\ * .gcno-o-name\ * .gcda | xargs rm-ffind. -name\ * .lo-o-name\ * .o | xargs rm-ffind. -name\ * .la-o-name\ * .a | xargs rm-f find. -name\ * .so | xargs rm-ffind. -name .libs-a-type d | xargs rm-rfrm-f libphp5.la sapi/cli/php sapi/cgi/php-cgi libphp5.la modules/* libs/* remarks. If it is installed for the first time, you can do the following: install to the specified directory cd / usr/local/src/ to download the source code package wget http://cn2.php.net/distributions/php-5.6.30.tar.gz and extract the source code package tar zxf php-5.6.30.tar.gz2. Create an account

The account is used to run the php-fpm service. In the LNMP environment, PHP appears as a service php-fpm, which exists independently in the Linux system and is easy to manage.

[root@gary-tao php-5.6.30] # useradd-s / sbin/nologin php-fpm3. Install PHP [root @ gary-tao php-5.6.30] #. / configure-- prefix=/usr/local/php-fpm-- with-config-file-path=/usr/local/php-fpm/etc-- enable-fpm-- with-fpm-user=php-fpm-- with-fpm-group=php-fpm-- with-mysql=/usr/local/mysql-- with-mysqli=/usr/local/mysql/bin/mysql_config-- with-pdo-mysql=/usr/local/mysql-- with- Mysql-sock=/tmp/mysql.sock-with-libxml-dir-with-gd-with-jpeg-dir-with-png-dir-with-freetype-dir-with-iconv-dir-with-zlib-dir-with-mcrypt-enable-soap-enable-gd-native-ttf-enable-ftp-enable-mbstring enable-exif with-pear with-curl with-openssl

The compilation parameter is different from the previous article, there is an additional enable-fpm, if you do not add this parameter, there will be no php-fpm file generation, let alone start the php-fpm service.

Error report:

Solution:

Yum install-y libcurl-devel

Note: if you install PHP for the first time, there will be a lot of dependent packages to install. If you read the error message, install whatever package is missing. 4. Compiling PHP [root@gary-tao php-5.6.30] # make [root@gary-tao php-5.6.30] # make clean & & make reports an error as shown below:

Solution:

# vim Makefile / / add "- lpthread" after-lcrypt

Solution:

# make clean & & make

5. Install PHP [root @ gary-tao php-5.6.30] # make install6. Modify the configuration file: [root@gary-tao php-5.6.30] # ls / usr/local/php-fpm/etc/pear.conf php-fpm.conf.default [root@gary-tao php-5.6.30] # cp php.ini-production / usr/local/php-fpm/etc/php.ini / / copy the configuration file (production is used in the build environment Development is used in the development environment) [root@gary-tao php-5.6.30] # ls / usr/local/php-fpm/etc/pear.conf php-fpm.conf.default php.ini [root@gary-tao etc] # vim / usr/local/php-fpm/etc/php-fpm.conf adds the following: [global] / / define the global parameter pid = / usr/local/php-fpm/var/run/php-fpm.piderror_log = / Usr/local/php-fpm/var/log/php-fpm.log [www] / / the name of a module listen = / tmp/php-fcgi.sock / / listening address listen.mode = 666 / / this line takes effect only if the listener is sock The permission used to define the sock file is 666user = php-fpm / / define the user of the service group = php-fpm / / define the user group of the service pm = dynamicpm.max_children = 20pm.min_spare_servers = 5pm.max_spare_servers = 35pm.max_requests = 500rlimit_files = 10247. It is normal to check the configuration [root@gary-tao etc] # / usr/local/php-fpm/sbin/php-fpm-t / / below.
